一、前言当前,国内外喷灌设备多采用中、高压力,即工作压力在4公斤/厘米~2以上,与地面灌溉比较,能源消耗较大,因此,在世界范围内能源危机波及各国的情况下,如何减少喷灌设施的能源消耗已成为影响喷灌技术继续发展的重要课题。我国近几年喷灌事业发展较快,原有以轻小型移动喷灌机组占绝对优势的情况已不适应喷灌事业发展的需要,迫切要求发展能源消耗少、喷洒质量高、适应性强的喷灌设备,所以近两年时针式喷灌机、平移式喷灌
I. Introduction At present, the domestic and foreign sprinkler equipment to use more and more high pressure, that is, the working pressure of 4 kg / cm ~ 2 above, compared with surface irrigation, energy consumption, therefore, the energy crisis in the world spread to all countries How to reduce the energy consumption of sprinkler irrigation facilities has become an important issue affecting the continuous development of sprinkler irrigation technology. In recent years, sprinkler irrigation developed rapidly in China. In the past, the situation that the light and small mobile sprinkler units dominated the development of irrigation and sprinkler irrigation was no longer adequate for the development of sprinkler irrigation. It was urgently required to develop sprinkler irrigation equipment with low energy consumption, high spraying quality and adaptability. Therefore, the past two years when the needle-type irrigation machine, translation sprinkler
